LUBRIOATOR.

SPECIFICATION formingpart of Letters Patent No. 791,418, dated May 30,1905.

Application filed April 13, 1904. Serial No. 202.941. I

To all whom it may concern.-

Be it known that I, WILLIAM A. HATGI-IER, a citizen of the United Statesof America, residing at Cleveland, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements inLubricators; and I hereby declare the following. to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

My invention relates to improvements in lubricators, and pertains moreespecially to a lubricator comprising a lubricant-receiving receptacleprovided at its lower end with several discharge-ducts arranged asuitable dis tance apart and in line laterally and means whereby thesaid ducts are successively supplied with grease or lubricant.

The primary object of this invention is to conveniently apply adequatepower to the lubricant-feeding head or piston on top of the grease orlubricant within the aforesaid receptacle to adequately and positivelyfeed lubricant from the said receptacle to each of the aforesaid ductsand to render the said receptacle chargeable with facility.

Another object is to construct a lubricator of the character indicatedwhich is simple and durable in construction, conveniently operated, andreliable in its operation.

With these objects in view my invention consists in certain features ofconstruction and combinations and arrangement of parts hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, largely incentral section, of a lubricator embodying my invention and shows thelubricator connected with several lubricant-conducting pipes. Fig. 2 isa side elevation of the externally-screw-threaded gear-bearing shaftemployed in actuating the lubricant-feeding piston or movablepressureexerting head of the lubricator and shows the said head ready tobe removed upwardly from the lower end of the shaft. Fig. 3 is averticalsection on line 3 3, Fig. 2, looking in the direction indicated by thearrow.

Fig. 1 is a top plan in section on line 4:4, Fig. 1. Fig. 5 is a topplan in section on line 5 5, Fig. 1.

Referring to the drawings, A indicates a vertically-arranged receptaclewhich is provided interiorly with a lubricant-receiving chamber a, whichis circular in cross-section.

Within and centrally of the chamber a (see and centrally of the top of ahorizontally-arranged box 13, which is integral with the receptacle Aand arranged below the gear I). The box 13 afiords bearing to acorrespondingly-arranged shaft O, which has also bearing in two boxes 14and 19, which are formed integral with the receptacle A and arranged atand a suitable distance from opposite ends, respectively, ofthe centralbox 13.

The shaft B rests at its lower end upon the box 13 around the bearing12, and the gear 6 is in mesh with the bevel-pinion 0, operativelymounted on the shaft O between the central box 13 and the end box 19,and the chamber a is enlarged downwardly, as at 15, between the saidboxes and around the said shaft to accommodate the location of thesaidpinion.

The shaft O extends through the end boxes 14 and 19 and is operativelyprovided at the outer end of the box 19 with a hand-wheel O for turningthe shaft. The receptacle A is provided at its upper end and exteriorlywith screw threads engaged by corresponding screw-threads formed uponand interiorly of the depending annular flange d of a cap D, whichcloses the said receptacle. The cap D is provided at its under side andcentrally with a depending bearing-forming cylindrical lug 16, whichprojects into and snugly but 12. By the construction hereinbeforedescribed it will be observed that the lugs 12 and 16 afford lateralbearing to the shaft P.

The piston or head G is mounted upon the shaft B and has a hub 0rcentrally-located sleeve 9 embracing the said shaft, which sleeve isprovided interiorly with screw -threads engaging with screw -threadsformed upon the shaft. The shaft B is screw threaded approximately itsentire length. The head G fits snugly but easily within the chamber aand is movable, as will hereinafter appear, endwise of the said chamber.The head G is prevented from turning with the shaft B, so that the saidhead will descend or ascend, according as the shaft is turned in the oneor the other direction.

The means employed for preventing turning of the head G with the shaft B(see Figs. 1 and 4) comprises, preferably, a metal strip 17, which isarranged vertically within and secured to the surrounding wall of thechamber rt. The member 17 extends the entire length of the path of thehead G and engages with a recess 18, formed in the said head, andthereby prevents the said head from turning upon the shaft B during therotation of the said shaft.

The shaftCis provided interiorly with apassage-way-forming bore 20,which extends longitudinally of the shaft from within the hand-Wheel-bearing end portion of the shaft to the outer end of the box 14,Where it is closed by an internally-screw-threaded cap a, which embracesthe outer end of the said box and engages corresponding screw-threadsformed upon and exteriorly of the said box. The shaft C is provided atthe outer end of the box 19 with an external annular shoulder 22, whichis overlapped by the inner end of a ring f, which loosely embraces theshaft C. The ring f is provided at its inner end with aninternally-screw-threaded annular flange 23, engaging correspondingscrew threads formed upon and exteriorly of the outer end portion of thebox 19. It will be observed, therefore, that the cap a and the ring fprevent endwise displacement of the shaft (J.

The receptacle A is provided at its lower end and next below the shaft Cwith four downwardly-discharging ducts 24, 25, 26, and 27, arranged asuitable distance apart longitudinally of the said shaft and in linelaterally, as shown in Fig. 1. The grease or lubricant supplied by myimproved lubricator is forced from Within the chamber a to and throughthe ducts 24, 25, 26, and 27 into the tubes or pipes P employed inconducting lubricant to axles or bearings to be lubricated. As shown inFig. 1, the ducts 25 and 26 are formed at the bottom of the central box13 and the ducts 24 and 27 are formed at the bottom of the boxes 14 and19, respectively.

The downward enlargement 15 of the chamber a. is in communication withthe interior passage-way 20 of the shaft C through two ports 28, formedin the surrounding wall of the said passage-way at opposite sides,respectively, of the said shaft, as shown in Fig. 5. The chamber (I, isalso enlarged downwardly around the shaft (J, as at 30, and the saiddownward enlargement 30 of the said chamber is in communication with theinterior passage-way 20 of the shaft 0 through two ports 32, formed inthe surrounding wall of the said passage-way at opposite sides,respectively, of the shaft. It will be observed that the interiorpassage-way 20 is continually in communication with the chamber (1/. Theshaft U is provided also in the surrounding wall of its interiorpassage-way 20 with as many ports as there are discharge-ducts leadingfrom the lubricator. The shaft U of the lubricator illustrated isprovided, therefore, with four ports 34, 35, 36, and 37, adapted toregister with the ducts 24, 25, 26, and 27, respectively. The ports 34,35, 36, and 37 are arranged, therefore, at suitable intervalslongitudinally of the shaft 0 and are spaced, furthermore, equidistantlycircumferentially of the said shaft. The arrangement of the ports 34,35, 36, and 37 relative to the ducts 24, 25, 26, and 27 is such that theports 34, 35, 36, and 37 shall during the rotation of the shaft 0successively communicate with the different ducts 24, 25, 26, and 27,respectively.

To facilitate the distribution of the lubricant within the passage-way20, the ports 23 communicate with the said passage-way between the ports36 and 37 and the ports 32 discharge into the said passage-way betweenthe ports 34 and 35.

The operation of my improved lubricator is as follows: The shaft 0 isrotated. Power is transmitted from the shaft C to the shaft B throughthe medium of the pinion c and the gear 6. The receptacle (1. is chargedwith grease or lubricant (not shown) by removing the cap D and the headG, whereupon the head G is introduced into the chamber (6 and the capDis replaced. The head G is prevented from rotation with the shaft B, ashereinbefore described, so that the head G during the rotation of theshaft B will descend and exert pressure upon the grease or lubricantcontained within the chamber (1/, and thereby force lubricant throughthe ports 28 and 32 into the interior passage-way 20 of the shaft C andthence into the ports 34, 35, 36, and 37. As already indicated, theports 34, 35, 36, and 37 discharge successively during the rotation ofthe shaft C, and consequently lubricant is adequately, positively, anduniformly fed to the different ducts 24, 25, 26, and 27 during eachcomplete rotation of the said shaft.

It will be observed that by the construction hereinbefore described theshaft B and the head G are free to be removed from the chamber aupon theremoval of the cap D. The shaft B and its gear I) and the head G aretogether lifted from the chamber a when the said head has descended intoits lowermost position within the said chamber.

The head G to facilitate its removal from the shaft B is dividedcentrally and longitudinally .of its sleeve 9 into halves or sectionshinged together at the bottom and adjacent the joint between the saidsections. Preferably each section of the head G is provided at its underside with cars 40, which are horizontally pivoted, as at 42,"to the earsof the other section of the said head. By this construction it will beobserved that the sleeve g of the head G is when the said head is in thechamber (I held in operative engagement with the shaft B by thesurrounding wall of the said chamber; but when the shaft B and head Gare removed from the receptacle A, as shown in Fig. 2, the two sectionsof the head G are no longer held closed together by the said wall andtilt downwardly by gravity, so

as to laterally open the sleeve 9, and thereby become disengaged fromthe screw-threads of the shaft B and render the said head free to belifted from the said shaft. In replacing the shaft B and head Gr withinthe receptacle A the shaft B is first placedin position with its gear 6in mesh with the pinion c whereupon the chamber cr is charged withlubricant, and thereupon the head G is applied. The shaft B extends asuitable distance. above the upper end of the receptacle A and above thestrip 17 and is preferably screw-threaded from its lower end upwardly toand above the said strip 17 to accommodate the placing of the head Gwith threads of the sleeve 9 in engagementwith threads on the shaftpreparatory to the engagement of the recess 18 during the application ofthe said head with the aforesaid strip 17, and the head Ghaving beenoperatively mounted on the shaft B is adjusted circumferentially tobring its recess 18 opposite the upper end of the strip 17 and held inthe required adjustment until the said recess during the lowering of thesaid head has engaged with the said strip 17 whereupon the cap D isapplied. The central portion of the cap bulges upwardly, as shown inFig. 1, to accommodate the extension of the shaft B the desired distanceabove the strip 17.
